Lazy Girl 

A sex position in which:

The man kneels up and leans back, taking his weight on his hands behind him. His partner lies back, with her head on a cushion. She bends her knees on both side of his hips and pulls herself forward so he can enter her, which will angle her vagina for optimal penetration. She has her hands free to caress her breasts and clitoris during sex.

My girl and I wanted to try something like missionary, but different, so we tried Lazy Girl.

Lazy Girlfriend 

When a male in a relationship ejaculates onto his female partners butt. This can be done while he is rubbing his penis in between her butt cheeks, or masturbating. If the girlfriend is too tired, not motivated, or busy with something else, she may let her male partner do this so she doesn't have to participate, yet her boy friend will be able to ejaculate.

Jenny was tired after a long day at school, so she gave her boy friend a lazy girlfriend

Stephanie was busy online, so her boyfriend Connor asked her politely for a lazy girlfriend
